Me and my bestie

“Son, Tenseiga can only call a person back from the dead once… It only makes sense. Life is not supposed to be limitless, after all. It’s not something that can be renewed over and over again for your own convenience. Sesshomaru, had you come to believe that you were a god, perhaps? That you did not need to fear death, as long as Tenseiga was in your hands? You needed to learn two things. The desire to save the life of a loved one taken by death, and the sorrow and fear which companies that loss.”
